DETAILED DESCRIPTION

[0032] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] With reference to Figure 1 , Figure 2 and Figure 4 , the present application provides an embodiment: a center prefabricated hole processing device, comprising an operating table 1, the operating table 1 is internally provided with a punching device 2, the operating table 1 is internally fixedly connected with a fixed frame 3, the fixed frame 3 is internally provided with a clamping assembly, and the operating table 1 equipment is provided with a cooling assembly; the clamping assembly comprises a fixed block 4, the side wall of the fixed block 4 is fixedly connected in the fixed frame 3, the fixed block 4 is internally fixedly connected with a sliding rod 5, the sliding rod 5 serves as the track of the sliding block 8, the side wall of the fixed block 4 is fixedly connected with a fixed column 6, the side wall of the fixed column 6 is rotatably connected with a rotating rod 7, the side wall of the sliding rod 5 is slidably connected with a sliding block 8, the side wall of the rotating rod 7 is rotatably connected with a connecting rod 9, the side wall of the connecting rod 9 is rotatably connected to the side wall of the sliding block 8, the side wall of the sliding block 8 is fixedly connected with a clamping plate 10, the clamping plate 10 is used for firmly fixing the to-be-punched article at a specified position, the side wall of the clamping plate 10 is fixedly connected with a rubber pad 11, the rubber pad 11 is used for increasing friction, the side wall of the fixed block 4 is provided with a hydraulic rod 12, the output end of the hydraulic rod 12 is connected with the sliding block 8 on one side, the operating table 1 is internally provided with a horizontal groove 13, and the side wall of the sliding block 8 is slidably connected in the horizontal groove 13.

[0034] When the device is used for punching, the hydraulic rod 12 is started, the piston rod of the hydraulic rod 12 is extended, thereby pushing the sliding block 8 to slide along the side wall of the sliding rod 5, the sliding rod 5 acts as a track for the movement of the sliding block 8, and provides guidance for the sliding block 8; when the sliding block 8 slides along the sliding rod 5 under the pushing of the hydraulic rod 12, the movement of the sliding block 8 drives the connecting rod 9 to move, the connecting rod 9 plays a role of connection and transmission of movement, and converts the linear motion of the sliding block 8 into the rotating motion of the rotating rod 7; the rotating rod 7 rotates under the driving of the connecting rod 9, and the rotation of the rotating rod 7 can change the positions of the two sliding blocks 8; when the rotating rod 7 rotates, the two sliding blocks 8 move towards the middle at the same time; in the process in which the two sliding blocks 8 move towards the middle, the sliding block 8 slides in the transverse groove 13, the transverse groove 13 provides a path for the movement of the sliding block 8, and ensures that the sliding block 8 can only move in a predetermined direction, thereby further improving the accuracy and stability of the clamping action; along with the movement of the sliding block 8 in the transverse groove 13, the clamping plate 10 connected with the sliding block 8 also moves, and finally the clamping and fixing of the object to be punched are realized; the clamping plate 10 is directly in contact with the object to be punched, and plays a role of firmly fixing the object to be punched at a specified position by applying pressure; the rubber pad 11 is fixed on the side wall of the clamping plate 10, and mainly plays a role of increasing friction; the rubber pad 11 has good elasticity and friction performance; when the clamping plate 10 clamps the object to be punched, the rubber pad 11 is in close contact with the surface of the object to be punched; the elasticity of the rubber pad 11 can make it better fit the surface shape of the object to be punched, increase the contact area, and at the same time, the high friction coefficient of the rubber pad 11 can provide sufficient friction to prevent the object to be punched from slipping during the clamping process, thereby further improving the stability of the clamping and ensuring that the object to be punched can always maintain a fixed position during the punching process, thereby providing a strong guarantee for accurate punching.

[0035] With reference to Figure 1 , Figure 3 and Figure 4 , the cooling assembly comprises a water tank 15, the bottom of the water tank 15 is fixedly connected in the operation table 1, a guide pipe 16 is fixedly connected to the side wall of the water tank 15, the guide pipe 16 plays a role of guiding the flow direction of water and debris, a water dripping groove 14 is arranged in the operation table 1, a water pump 17 is fixedly connected in the operation table 1, a conveying pipe 18 is fixedly connected to the inside of the water tank 15, a connecting pipe 19 is fixedly connected to the output end of the water pump 17, the connecting pipe 19 penetrates through the side wall of the operation table 1, a fixing sleeve 20 is fixedly connected to the side wall of the connecting pipe 19, the fixing sleeve 20 is fixedly connected to the side wall of the operation table 1, a spray head 21 is fixedly connected to the side wall of the connecting pipe 19, a drainage pipe 23 is fixedly connected to the side wall of the operation table 1, the drainage pipe 23 is fixedly connected to the inside of the water tank 15, and a filter plate 22 is slidably connected in the water tank 15, the filter plate 22 is used for intercepting debris and impurities in water;

[0036] When the punching operation is performed, the punching device 2 continues to operate at high speed, and the strong friction between the drill bit and the workpiece generates a large amount of heat. At this time, the water pump 17 is started, and the cooling liquid in the water tank 15 is pumped out through the delivery pipe 18. The extracted cooling liquid is then delivered through the connecting pipe 19, so that the cooling liquid is delivered to the spray head 21. The spray head 21 can uniformly disperse the cooling liquid into fine water droplets, which are sprayed to the punching device 2. These fine water droplets can quickly contact the surface of the punching device 2 and carry away a large amount of heat through heat exchange, effectively reducing the temperature of the punching device 2 and keeping it within the normal working temperature range, ensuring the stable performance of the punching device 2. Subsequently, the water and debris falling from the surface of the punching device 2 enter the guide pipe 16 through the water drain groove 14 opened in the operation table 1. The operation table 1 is the operation platform for the entire punching operation. It not only provides support for the placement and fixation of the workpiece, but also undertakes the function of guiding the discharge of water and debris. The water drain groove 14 is opened in the interior of the operation table 1, which can effectively collect the water and debris falling from the punching device 2, preventing them from splashing everywhere and keeping the working environment clean. The collected water and debris flow into the guide pipe 16 along the water drain groove 14. The guide pipe 16 guides the flow direction of the water and debris. It is connected between the operation table 1 and the water tank 15, ensuring that the water and debris can smoothly enter the interior of the water tank 15 from the water drain groove 14. After the water and debris enter the interior of the water tank 15, the filter plate 22 installed in the water tank 15 begins to play a role. The filter plate 22 has a fine mesh structure that can effectively intercept debris and impurities in the water, allowing only filtered clean cooling liquid to pass through. Through the filtration of the filter plate 22, the impurities in the cooling liquid are separated out, allowing the cooling liquid to be reused. This not only saves the amount of cooling liquid used, reduces production costs, but also reduces environmental pollution and achieves effective use of resources. After a long time of use, the filter plate 22 will accumulate a large amount of debris and impurities on the surface of the filter screen, affecting the filtering effect. At this time, the filter plate 22 can be pulled out by the handle for cleaning. With multiple cycles of cooling liquid use, although the filter plate 22 can filter out most of the impurities, some small particles and dissolved substances that cannot be filtered out will still remain in the water, causing the water quality to gradually decrease. When the water quality decreases to a certain extent and cannot meet the requirements of the cooling system, the water can be discharged through the drain pipe 23. The drain pipe 23 is connected to the bottom of the water tank 15. By opening the valve, the cooling liquid with decreased water quality in the water tank 15 can be discharged through the drain pipe 23, so that new cooling liquid can be replaced in time to ensure the normal operation and cooling effect of the cooling system.

[0037] Working principle: When the device is used for punching, the hydraulic rod 12 is started to push the sliding block 8 to slide on the side wall of the slide rod 5, causing the connecting rod 9 to rotate and drive the rotating rod 7 to rotate, causing the two sliding blocks 8 to move towards the center, causing the sliding block 8 to slide in the horizontal groove 13, causing the clamping plate 10 to clamp and fix the object to be punched. The clamping plate 10 has rubber pads 11 fixed on the side wall, which increase the friction.

[0038] Since the punching device 2 generates high heat during operation, the water pump 17 is started at this time, the cooling liquid inside the water tank 15 is pumped out through the conveying pipe 18, and then is conveyed to the spray head 21 through the connecting pipe 19, the water flow is sprayed to the punching device 2 by the spray head 21 to cool down, and then the falling water and debris enter the guide pipe 16 through the water dripping groove 14 opened inside the operation table 1, and then are guided into the inside of the water tank 15, the filter plate 22 is arranged inside the water tank 15, and the water is recycled through the filtration of the filter plate 22, when the filter plate 22 needs to be cleaned, it can be pulled out through the handle to clean, and the water quality decreases after multiple cycles, at this time, the water can be discharged through the drain pipe 23.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or equivalent replacement of some of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the scope of protection of the present application.
